Along with the development of society, the significance of water resource more and more is familiar with by people.Lack the country of freshwater resources, the major issue how using water wisely has become present people extremely to be concerned about at us.On water consumption, farmland irrigation water is one of rich and influential family of present water.The main mode of current field irrigation has following three kinds: a kind of is wild-flooding method; The 2nd, low pressure pipe irrigation method (claiming " pipe is irritated " again); The 3rd, sprinkling irrigation, slight irrigation method.Because China's freshwater resources are fewer, imbalance between supply and demand becomes increasingly conspicuous.For using water wisely, the casual method of irrigating of open channel will be eliminated gradually." pipe is irritated " and sprinkling irrigation and slight irrigation will become main irrigation method." pipe is irritated " and the water of sprinkling irrigation and slight irrigation all are to use line transportation, and pipeline is embedded in underground, and both using water wisely do not account for the arable land again, are the irrigation methods that present emphasis is promoted.From under ground piping, water released and under ground piping between connection need control with valve, promptly discharging water needs use discharging valve, the pipe branch place will establish shunt valve, damming on the main pipe needs shutoff valve, therefore the valve quantity of needs is many especially.It has not only increased the investment to delivery line, has increased the weight of peasant burden, and uses also inconvenient.The valve that generally adopts is a gate valve at present, and manufacture cost is also than higher.
The purpose of this utility model is to provide a kind of plumbing valve that discharges water, divides water to dam three kinds of functions that has in the under ground piping irrigation of farmland, and this valve mechanism is simple, easy to operate.
The utility model is to realize like this, it comprises that its side has the blind hole tubular type valve body of water intake and water outlet, it is characterized in that: a piston valve core is installed in this valve body inner bore, is installed with a bonnet in the upper end of valve body, bonnet is provided with the dewatering outlet.A horizontal rotating shaft also is installed on bonnet, and at least one end of this rotating shaft has the joiner that is connected with handle.Be fixed with one at the middle part of this rotating shaft and turn handle, turn the other end of handle and an end of connecting rod and be hinged, the center, upper-end surface of the other end of connecting rod and the piston valve core formation that is hinged.
This valve working principle is: the water intake of valve body taps into waterpipe, and its water outlet connects the distributed water pipe road, and the dewatering outlet connects the irrigation water band, and a handle is installed on the end joiner of rotating shaft.If when intake pipe is ended, as long as by rotating shaft, make it drive piston valve core through connecting rod, make piston valve core be positioned at the water inlet, block water intake with the side of spool and get final product.If when moisture flow to the distributed water pipe road, rotating shaft, make its through turn handle, connecting rod drives piston valve core and moves up, water intake is communicated with water outlet through the inner chamber of valve body gets final product.If discharge water when irrigating by this valve, again rotatingshaft make its through turn handle, connecting rod drives piston valve core and moves down, and piston valve core is moved on in the valve opening between water intake and the water outlet, and water intake is connected with the dewatering outlet, irrigation just can discharge water.
Owing to adopted piston valve core in the valve body of the present utility model, by the slip of piston valve core in valve body, can realize the irrigated farmland of closing, shunt and discharge water of groundwater supply pipeline, thereby increase its function of use.This valve can replace 2-3 gate valve in the former underground pipe network, and therefore the investment that can save pipe network widely alleviates peasant's burden.The inner chamber of this valve body adopts straighttube-type, and it is relatively simple for structure.Operate the slip of spool by rotating shaft, use also more convenient.This plays a positive role for the modernization that promotes the agricultural water conservancy irrigation.
Fig. 1 is the utility model plan view;
Fig. 2 is an internal structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
Valve body 6 of the present utility model is blind hole pipes, and what its diameter was bigger can form with concrete prefabricated, and little can make cylinder iron or plastic tube.Be provided with a water intake 1 on the top, side of valve body 6, be provided with a water outlet 8 in its bottom, side.A piston valve core 7 is installed in the endoporus of valve body 6.Be installed with a bonnet 3 in the upper end of valve body 6.The side of bonnet 3 has dewatering outlet 2, and a horizontal rotating shaft 4 is installed on bonnet 3, and at least one end of rotating shaft 4 has the joiner that can be connected with handle.This joiner can be a crosshead, also can be regular polygon, as equilateral triangle, square, regular pentagon, regular hexagon etc.Said handle can be a rocking handle, can be handwheel also, has on it and the corresponding attachment hole of joiner.Joiner can be a pin-and-hole also, is processed with corresponding pin-and-hole on handle, connects through bearing pin then.Be installed with one at the middle part of rotating shaft 4 and turn handle 11, turn the outer end of handle 11 and an end of connecting rod 5 and be hinged, the center, upper end of the other end of connecting rod 5 and piston valve core 7 formation that is hinged.
Owing to turn handle 11 and be fixed in the rotating shaft 4, turn and be hinged with connecting rod 5 on the handle 11 again, so rotating shaft 4 can only drive turn handle 11 from turn handle 11 be positioned at rotating shaft 4 under turn to the side top, use some inconvenience.In order to make rotating shaft 4 carry out 360 degree rotations, can with rotating shaft 4 with turn handle 11 and make one, make it to become bent axle and connecting rod and carry out hingedly, promptly turn handle 11 and partly replace by the bent axle of rotating shaft 4.
